GAS-LIGHTING- DEVICE.

Specification of Letters Patent. Patented NOV. 28, 1911.

Application filed December 8, 1910. Serial No. 596,363.

To all whom it may concern:

Be it known that I, JAMES M. CRowNER, a citizen of the United States,residing at Ottumwa, in the county of Wapello and State of Iowa, haveinvented certain new and useful Improvements in Gas-Lighting Devices, ofwhich the following is a specification.

My present invention relates particularly to devices for electricallylighting gas burners and my primary object is to provide a novel andinexpensive lighter, in which all springs and other delicate parts whichare subject to quick wear, and likely to get out of order, are done awaywith.

A further object of my invention is to provide a movable contact pointfor the. striker arm, so constructed and counter-balanced, that italways hangs at the proper position for use, and in such manner that nosprings or other additional means are necessary to maintain it in suchposition.

A further object of my invention is to provide a laterally adjustablesupport for the counter-balanced contact, having an offset to form aclearance between the burner and its body portion, for the free and easymovement of the counter-balancing weight.

A still further object of my invention is to provide a striker arm solocated and connected upon the valve stem that it will not interferewith the operations of the valve key, and will permit of ready removalfor the purpose of substitution.

With these and other objects in mind my invention, therefore, resides inthe features to be hereinafter described and particularly pointed outwith respect to the accompanying drawing, forming a part of thisspecification, and in which,

Figure 1 is an end elevation, and Fig. 2 is a side elevation.

Referring now to these figures, 5 designates the lower or valve portionof a burner upon which is screwed, as usual, the burner 6 carrying a tip7 at its upper end. Transversely through the valve portion 5 extends avalve stem, upon one projecting end of which a nut 8 is threaded, andupon the opposite end of which is secured the button or key 9 by whichthe valve stem is actuated to turn on, or cut 0E, the flow of gas.

The striker arm 10 which I provide, has a lower and inwardly offset end11 which is curled about and secured to the washer or nut 8 and is,therefore, positioned at one side of the burner farthest from the key orbutton 9. The upper angular end 12 of this arm extends above the burnertip 7 and has a swinging movement thereabove when the key or button 9 isturned.

Clamped between the burner 6 and the valve portion 5 is a disk 13,having an up wardly projecting tongue 14: between said burner 6 and thestriker arm 10, and in line therewith, the upper portion of said tonguebeing in the form of a lateral extension 15, upon which is adjustablysecured the lower end of a vertical supporting arm 16, and between whichand said lower end of said arm 16 is disposed an insulating material 17.The upper and inwardly ofl'set end 18 of said arm 16 supports the pivot19 of the contact arm 20, the upper end of which contact arm is in theform of a tapering finger 21, the upper end of which is alwaysmaintained in the path of swinging movement of the upper end 12 of thestriker arm, and the lower end of which contact arm is in the form of acounter-balancing weight 22 which swings in the space between thevertical arm 16 and the burner 6.

From the foregoing it will be seen that as adjustment of the supportingarm 16 upon the extension 15 in order to cause the upper portion 12 ofthe said striker arm to pass over, and disengage from, the said finger21 of'the said contact arm at a point adjacent and vertically above theburner tip 7, which is desired. Therefore, it being of course understoodthat the upright arm 16 and the striker arm 10 are connected to oppositepoles of a generator, it will be seen that the disengagements of thesaid striker arm and the finger 21 will break the circuit previouslyestablished upon their contact, and thus de velop a spark which willignite the gas flowing from the burner tip 7. The counter-balancedcontact arm thus does away with all springs and other delicate partsusually employed, and the lateral adjustability of its uprightsupporting arm renders it easy to regulate the igniting spark in properrelation to the burner tip without bending or twisting either of thecontact members as is usually necessary.

I claim:

The combination with a lighting fixture including a burner and a valve;of an arm movable with the valve and having a laterally extendingextremity projecting across and above the burner tip, a support mountedon the fixture, an upstanding arm secured to the support, and having anofiset at its upper end toward theburner, a contact device pivoted tothe offset portion of the upstanding arm and having a finger extendinginto the path of the laterally extending extremity of thefirst-mentioned arm, and movable thereby across and above the burnertip, said parts swinging in different arcs and separating at a pointabove and adjacent to the burner tip, and a counterweight for thecontact device, said counterweight being located in the space betweenthe burner and that portion of the upstanding arm which is below theoifset thereof.

In testimony whereof I aflix my signature in presence of two witnesses.

JAMES M. CROWNER.
